In college M the average (arithmetic mean) number of students per course is 30 and the ratio of the number of students to the number of faculty is 20 to 1.

Quantity A: The total number of students in College M

Quantity B: 600

Each piece of information is insufficient to determine the total number of students.

The average (arithmetic mean) number of students per course is 30To determine the number of students, we need to know the number of courses.

The ratio of the number of students to the number of faculty is 20 to 1To determine the number of students, we need to know the number of faculty.

Consider these two possible cases:

Case #1: There are 3 faculty members, who teach a total of 2 courses. This means there are

60 students in College M, in which case Quantity B is greater.

Case #2: There are 300 faculty members, who teach a total of 200 courses. This means there are

6000 students in College M, in which case Quantity A is greater.

Answer:

Cheers,

Brent
